Medium-Pressure Material Pump

Description

The major components of the pump models in the 

7896 series consist of a reciprocating air motor and a 
double-acting pump tube. The pump tube is divorced 
from the motor which:

• protects the motor from product contamination
• allows separation without product leakage

The pump tube is designed to enable the delivery of a 

variety of materials. These medium-pressure (22:1) 
pumps contain a bung adapter [2 " NPTF (m)] that allows 
operation directly from original drums or bulk containers.

Models 7896-A5 and 7896-B5

Each pump model is designed with a pump tube length 

to accommodate different size containers. See Figure 1

NOTE: Each model can be hoist-mounted.
Refer to Page 2 for details.
